There are many 2 bedroom flats in Glasgow advertised as 'offers over' £80,000, but as a previous poster said, Scottish property often sells for a lot more than the asking price. Your friend really needs to talk to estate agents, to find out what's realistic at the moment.
She'll need a Scottish solicitor, too.
Also, these cheap flats will not be in the most desirable or central parts of Glasgow - I don't mean crime etc (though there are a few rough areas), rather, they will be near very busy, dirty roads or industrial sites or above shops, or will be rather run down.
But - plus side - some of these flats will be in nice, substantial buildings, either Victorian tenements or 1930s 'cottage'-style, with gardens. There are also modern flats, too.
I am absolutely not an expert, but parts of formerly rough/poor/neglected Glasgow have been transformed in recent years. The example I know best is Dennistoun, which now has a conservation area and interesting shops and restuarants (and a lovely park nearby). I doubt very much whether there are flats (except very small) that sell for under £100,000 there, though there is this:

and this

Your friend might find something larger slightly further to the east - in Carntyne/Riddrie, for example:

But I think your friend is probably hoping for something much bigger/grander.
Glasgow has good public transport, and, I know it is a cliche, but in my experience as a regular visitor, I have always found it very friendly. It's got great (free/cheap) musuems/art galleries, parks and gardens, libraries, - and music and theatres etc etc.
But as others have said, to make so big a change, your friend really needs to visit lots of different places to see what's available there.
